We got there at 9.45 on a sunday in summer holiday, it was not too bad a crowd. We went with froiends as a group which worked out cheaper(Obviously, cannot beat getting the annual pass deal). Started off with the busy rides, and kept water plays and rides to the end.
highly recommed(for both adults and kids) to do the surfers, jet ski and any rides you can get on to :-).
Miniland and pirate show added to more enjoyment.
Get in early, and leave as late as possible. Kids slept on the way back home holding the legos they bought from the lego shop :) and we were happy parents to have a quiet night..
